CHARLES W. HUNT, OF NEW YORK, N. Y.; KATHARINE H. HUNT, CHARLES WALLACEHUNT, AND GEORGE S. HUMPHREY EXECUTORS OF SAID CHARLES W. HUNT,

DEcnAsED:

To all whom t may c0acern.'

Be it known that I, CHARLES hunnen HUNT, a citizen of the United States,residing in Stapleton, in the borough of Richmond of the city of NewYork, in the State of New York, have invented certain new and usefulImprovements in Conveyers, of which the following is a specification,reference being had to the accompanying draw ing, forming a part hereof.

This invention relates to bucket conveyers, in which dumping buckets arecarried by endless chains and it has for its object to provide improvedmeans for dumping the buckets. Heretofore such means have been soconstructed as to subject parts of the mechanism to such heavy blowsthat they are liable to be broken unless they are made unduly heavy andit is the special purpose in t-he present case to so construct thedumping devices that they shall be able to withstand the heavy blows towhich they are necessarily subjected without being unduly heavy.

The invention will be more fully explained hereinafter with reference tothe accompanying drawing in which the single figure is a view inelevation showing so much of a conveyer as is necessary to enable theapplication of the invention thereto to be understood.

In the arrangement shown, the usual conveyer chains, one of which isshown at a, are provided with wheels b to travel on rails c and supportbetween them, upon transverse shafts or trunnions (Z, the dumpingbuckets e. Each bucket is provided with a cam like dumping flange f, theshape of which will be varied to accord with the shape of the dumpingdevices and with the desired movement of the bucket in dumping.V

Upon the frame members, one of which is shown at g, is mounted insuitable bearings a rock shaft L which has secured thereto a lever z' bywhich the shaft may be rocked, and a crank arm 7c which is preferablyprovided with a stop Z to cooperate with a link m which is pivoted onthe arm lc. To the other end of the link m is pivotally con nected adumping bar fn, which is pivotally mounted at its other end, as at 0,upon the frame member g. It will be observed that the arm and linkconstitute a toggle between the frame and the dumping bar. The shape ofthe dumping bar may be varied to accord Specification of Letters Patent.

with the dumping flanges or cams onthe buckets and with the desiredmovement of the buckets in dumping, but it is relatively long, as shown,and is mounted at one end in a suitable bearing on the frame while itsother end is supported, in operative position, by the shaft 7L with itsarm Z: and the link m, being inclined in a direction opposite to that ofthe movement of the approaching bucket, so that the shock of the loadedbucket, moving at considerable speed, against the dumping bar, istransmitted longitudinally through the bar and its bearing to the frame,and the danger of breakage which exists when the dumping arm is secureddirectly to the shaftjlz., as is usually the case in conveyors of thisclass, is eliminated. The dumping bar is easily moved into or out ofoperative position by partial rotation of the shaft h, as clearlyindicated in the drawing, in which the positions which the parts assumewhen the bar is not in operative position are indicated by dotted lines.

It will be observed that the center of the joint between the arm 7c andthe link m, when the dumping arm is in operative position, standsslightly beyond the line joining the centers of the shaft /L and thejoint between the link m and the dumping arm n, and that vthe stop Z,coperating with the link m prevents further flexing of the two membersin the same direction. The dumping arm is thus locked automatically inoperative position by the coperation of the stop Z with the link m sothat there is no necessity for any fastening of the operating lever z'.

I claim as my invention:

1. The combination with a conveyer, comprising chains and dumpingbuckets mounted thereon and having dumping flanges, of a frame, adumping bar pivoted at one end upon the frame, a shaft mounted on theframe and having a crank arm, a link connecting the crank arm with thedumping bar, said arm and link constituting a toggle between the frameand the dumping bar and means to limit the movement of the crank arm. A

2. The combination with a conveyer, comprising chains and 'dumpingbuckets mounted thereon and having dumping flanges, of a frame, adumping bar pivoted at one end upon the frame, a shaft mounted on theframe and having a crank arm, and a link connecting the crank arm withthe dumping bar, the crank arm having a stop plate to coperatie with thelink to limit the movement of the crank arm.

3. The combination With a cO-nveyer comprising chains and dumpingbuckets mounted thereon and having dumping flanges, of a frame, arelatively long dumping bar pivoted on one end on the frame, the otherend being curved to accord With the dumping flanges and means to throwthe bar in operative relation to the buckets, said means being in asubstantially vertical plane whereby the shock of the impact of thebucket against the bar is transmitted through the bearing of the latterto the 15 frame.
